Luk 5:33 Then they said to him, “John’s disciples regularly fast and pray, and so do the disciples of the Pharisees, but yours continue to eat and drink.”
Luk 5:34 So Jesus said to them, “You cannot ask the wedding guests to fast while the bridegroom is with them, can you?
Luk 5:35 But those days are coming, and when the bridegroom is taken from them, at that time they will fast.”
Luk 5:36 He also told them a parable: “No one tears a patch from a new garment and sews it on an old garment. If he does, he will have torn the new, and the piece from the new will not match the old.
Luk 5:37 And no one pours new wine into old wineskins. If he does, the new wine will crack the skins and will be spilled, and the skins will be destroyed.
Luk 5:38 Instead new wine must be poured into new wineskins.
Luk 5:39 No one after drinking old wine wants the new, because he says, ‘The old is good enough.'”

what the new wine is

Jesus was not against fasting. He had fasted himself, in preparation for entering his ministry, and during his times of retreat and seclusion during his ministry. So, just branding all the old traditions as old wine, and going after new traditions is a misapplication of this text. Instead, Jesus warns against holding on to traditions which fail to accomplish their intended purpose. The disciples were not waiting for the Holy Spirit to move. He was moving in the person of Christ, so the disciples had no time to isolate themselves in preparation for anything. Being with Jesus was the new wine.

LORD, give us the new wine of your presence, and may we never forsake that experience for another.
